Team captain Judy Murray is targeting a decisive victory against Ukraine in order to recover the damage.
She said: "The Turkish girls really raised their level. But they were both winnable matches for us.
"Jo had two set points in the second set and didn't manage to get them. Perhaps if she'd got that set she might have managed to find a way to pull the win out.
"Heather did a good job after a slow start and just fell away at the end. I know she was very disappointed to lose that match.
"If we win 3-0 tomorrow against Ukraine we will win the group, which has to be our goal."
